I've installed vicibox11 on a Virtualbox VM as a testing sandbox with Dinstar GSM Gateway 32port.
8GB RAM 40GB storage and 4Core CPU
The system and VM are connected to the local network on a D Link switch (1210-28p 24 port poe switch) using a D link WiFi USB (DWA 182 Wireless AC1300 MU-MIMO WiFi USB).
The gateway is connected on LAN to the switch.
The latency is minimal at ~4ms from agent system and VM and then ~2ms from VM to Gateway, the jitter is very minimal <5ms too.
I've no idea what is causing the quality to be subpar.
